\ IMPROVEMENT IN PEG-GING-JACKS.

The Schedule referred to in chose Letters'Patent and making part of thesame.

To all persons to whom these presents mag/ come Be it known that I,HUBERT RICARD, of Haverhill, in the countyof Essex and State of'Massachusetts, have invented a new and useful Impi'ovement-inPegging-.lacizs; and do hereby declare the same to be fully described inthe following specication and represented in the accompanying drawing,ot wnich- Figure l denotes a side elevation, and

Figure 2 alongitudinal section of a jack constructed naccordance with myinvention,and havingalast applied thereto.

Figure 3 is a top view of the eccentric or double cam-plate.

Figure 4 isa top view of the upper hinged plate or base, on which the'cam-plate is supported and turns.

Figure 5 represents the ja'ck in a position at right angles to thatshown in fig. 1. My inventionhas reference to that class of devicestermed shoemakers head-blocks, in which the jacking or fastening of thelast is eiected by lsimply rotating the turn-plate on which the last issupported, and consists in the'peculiar construction and arrangement ofits parts, as hereinafter described. A

Also, in the peculiar construction and arrangement of devicesforjackingor fastening the last.

Also, in combined latch and coupler applied to the cam-plate, in mannerand for the purpose hereinafter stated. f I

Also, in 'thefpeculiar mode ot' connecting the top and'cam-pl'ates tothe upper hinge-plate, whereby the two former may be rotatedv upon thelatter without a liability of becoming either .set or disconnected,y asthey lwould were a simple screw cut upon the spindle, and a n ut appliedthereto.

In the said drawing-` a A denotes the hase-plate of the jack, which isformed of metal, and is to be Iirmly secured to the top of a pedestal,or other proper part of a shoemakers bench.

Over-lying the said plate, and hinged thereto, is another 'flanged plateo1' disk, B, which has a series' of cylindrical holes, a, made in it, toreceive a couplingpin or stud, b, to be hereinafter described.

The said -plate has a cylindrical hole, B', made through it. O n theun'der side of the said plate, and around the said hole thereof', anannular chamber, c, is formed, to receive a circular` disk' or washer,d, in

whose upper surface is made a square socket, to receive thecorrespondingly-shaped lower end of a spi-ndle or projection, O,extending down from the top plate D, the said disk being connected tothevsaid spindle by a screw, j'.

Bymeans of the said spindle and washer, the top plate and the cam-plateare so connected or pivoted to the hingeplate B as to be capable ofbeing either rotated upon the latter plate, or of permitting the wholeto be turned bodily up into the position shown v in fig. 5. v

E is a hollow boss or projection, which extends upward from the centralpart of the plate B, and has an annular shoulder, g', made thereon, theupper endV o' constituting a journal for the hub or annular projection hof the plate C, which vis arranged directly over it, and so as to becapable ot being rotated thereon, as occasion may require.

The said plate (l is formed with apeculiar eccentric or doublecam-groove, S, extending around the annularfprojection lli, as seen iniig. 3. This groove is formed eccentric on each side of the axis orcenter of motion of thc said plate.A

The said groove receivesthc lower end f' of a curved two-armed lever, G,which is pivoted to a bifurcated heel standard, H, projecting up fromthe said top plate, as shown in tig. 1, the upper arm g constituting theheel-pin for supporting the heel of the las't.

The object of the said double' eccentric or cam-groove is to enable thelastto be fastened or jacked, whether the top pla-te be rotated to therightor left.

Furthermore, there is affixed to the top of the said plate C a combinedspring latch and coupler, the said coupler consisting of a piu or stud,b, which extends downward at a right angle from -the latch b', andthrough a slot made down through the said plate. The said latch isarranged horizontally, and projects beyond the outerface of the plate C,and works up and down wi thin a "ertical slot made through the flangedrim le of the plate. By pressing the said latch downward, the stud orcoupling-pin l1 will be forced into some one of the series of holes aot' the plate 13, and will lock the said cam-plate C rmly to the plateB, so as to pre vent any rotation thereof', whenever circumstances mayrequire.

The said top plate has a series of notches, o2, formed on its underanged'snriace, to operate in connection with the spring latch beforementioned, the object of such spring latch being to maintain the topplate in firm connection with the cam-plate, in whatever position it maybe set.

v'K is the toe-rest or supporter, which is applied to two standards L Lprojecting up from the upper surface of the plate D, in-'the usualmanner.

M is a last, applied to the jaclr.

From the above it will be seen that the topplate D and the cam-plate' Care so connected or pivoted to the upper hinge-plate B as to be freelyrotated thereon, while the hinge enables the whole to be readily turnedfrom a horizontal into a perpendicular position, so as to enable aworkman to more conveniently get at the edge of a shoe when on the last,to perform the necessary manipulations thereon.

The said hinge-plate B has a stop or projection, N,

axed to its rear side, which, whenthe said plate. is

raised from a horizontal into a vertical position, rests uponaprojection, p, extending from the hase-plate A, and, arresting itsfurther advance, maintains it in such position. l

, v It will also be seen that the combined latch and coupler,constructed and arranged as described, perforni the double function oflocking the cam-'plate to 'the hinge-plate, and allowing the top-plateto be rcvposition shown in tig. 1, and the lower end of the lever VGr tohe at the point j n, or within the circular -part of the groove S, thelast can be easily placed upon the heel-pin and toe-rest of the jack.'In order to secure the said last firmly to the jack, I first press downthe spring latch, so as to release the top plate from the cam-plate.stud bintoone of the sockets a of the hinge-plate B, and`therehylocksthe cani-plate rigidly thcreto.- Next, I rotate the'topplate either to the right or left until thelast has .become sniiicientlytightened or secured, when the elastic action oi the latch 1r' willwithdraw the coupling-pin-i'om the hinge-platc,and, at the same time,the latch willhe forcedinto one of the notches c of the said top plate,releasing the cam-plate from the hinge-plate, and thereby locking thesaid cam-` plate firmly to the top-plate. Under this arrange# ment, thesaid cam and top plates canA be readily ro. tated through an entirecircle, so as to bring a shoe, when upon the last, into the mostconvenient position for being'fpegged, or having its ysole secured tothe np- This operation forces the coupling-pin or per. After the shoehas been pegged, the jack may be turned down, so as to bring the edge ofthe sole into a horizontal position, in order to enable the operator orworkman to trim or pare the edges thereof, which, when effected, thejack may be turned into its former position. ITo remove the last fromthe jack, I have simply to press-down the spring latch, so as to releasethc top plate from the cam-plate, and next rotate the said top plate ina direction opposite to that in which it was moved to fasten thelast, orback'into the positon'shown in fig. 1, whenthe last can' beeasilyremoved.

' I do not claim theinvention described in Letters Patent No. 22,340, nor any of the devices shown there -l in lbut Y i What I claim is asfollows:

1. My improved pegging-jack, consisting of `the plates A B O D, thelever G, and the toe-sifpporter K, all constructed, combined, andarranged together, in manner and so to operate as set forth.

s 2. As a means of jackingthe last, the lever G, the cam-plate O, andtop plate D, all constructed, conibined, and arranged, in manner and soas to operate as set foith.

3. The' combined spring latch and coupler, in coinbination'with the topplate D, the cam-plate O, and the hinge-plate- B, when all the saidparts are constrnctedand arranged in manner as described, and so Vas toloperate as andfor the purposes specified.

' 4. "lhemode of connecting or pivoting the plates Gand D to thehinge-plate B, viz., by means of the spindle p0, the washer d, and thescrew f, constructed,-

combined, and arranged together in manner as described.
